IMPROVEMENT IN GRAIN-METERS.

Specification forming part of Letters Patent No. 215.160, dated May (3,1879; application filed October 5, 1878.

To all whom it may concern:

Be it known that I, EDUARD REISERT, of Cologne, Prussia, have inventednew and useful Improvements in Automatic Scales, of which the followingis a specification.

The nature of my invention consists of an improvement on the automaticweighing-machine for which an application has been filed by me on the17th day of May, 1878, and relates principally to the arrangement forclosing the hinged bottom of the weighingvessel.

In the accompanying drawings the two figures represent side views ofparts of the machine embodying my invention, to be referred to moreparticularly in the following description.

Similar letters represent similar parts.

The operation of the valve E, which closes and opens the mouth of thehopper T, acted upon by its arm 0 on one side in contact with the end ofthe beam-arm A, and at the other side by the pin Z, attached to thevalvearm D, and operated by the fork-piece f, in connection with the arm9 and lever Z, is similar, as fully described in my application filedMay 17, 1878; and the operation of the lever Z, with its arm g, actedupon by the beam-arm A, locked during a certain time of the operation ofthe scales by means of the arm X, which latter, when the scales turn andthe projection 0, attached to the weight G, is then disengaged from saidlever Z, whereby this lever Z is allowed to fall, striking theprojection g; on the lever V to open the hinged bottom I) of the vesselB, is likewise similar and substantially the same described in myapplication of May 17, 1878.

The lever V turns on a pin, 1), firmly attached to the vessel B, and hason one end a projection, y, and at its other end a projection which maybe provided with, a friction-wheel, M. The arms of this lever V areturned upward, forming a U, to bring the projections y and M in theproper positions to be acted up on by the lever Z.

To the hinged bottom I), turning on the axis 0 a lever, P, is attachedconnected through a link or rod, L, with the lever V. Suitable weightsmay be attached to the bottom Z) to counterbalance the same, itrequired.

During the time the vessel is being filled, and when the bottom bis inthe position shown in Figure I, and has closed said vesselB, the centerof the connecting-pin 2, which connects the link L to the lever V, issituated a little below a line passing through the center 0E pin 1) andthe center of pin 3. The link L and that part of the lever V from p to 2form, therefore, a joint operating similar to a togglejoint; and as longas the center of the pin 2 is situated below the line passing throughthe center of pin p and the center of pin 3 thelever P will be heldfirmly in its position, and prevented from moving, independent of theweight which may be placed upon the bottom I); and as the lever P isfirmly attached to the shaft 0, upon which the bottom I) is likewisefirmly attached, this bottom I) will be retained in this position,closing the vessel B until the above-described position of the pin 2 ischanged.

When the vessel 13 has been filled with the desired fixed quantity ofmaterial, and the scale-beams turn, the projection c on the weight 0comes in contact with the lever X, as described in my formerabove-mentioned specification, and relieves thereby the lever Z,allowing the same to fall, and, coming in contact with the projection yon the lever V, causes the same to move or turn on its center p, therebymoving the joint 2 above the line passing through 1) and 3, when theweight resting up on the bottom I) will cause the same to open easily todischarge the contents of the vessel 13.

When the vessel 13 has been emptied the weight 0 will turn the beam-armsA, bringing thereby the end of the beam-arm A against the arm g,connected with the lever Z, and cause thereby said lever Z to move orswing again upward, at the same time coming in contact with theprojection or wheel M. (See Fig. IL) This swinging motion of said leverZ will cause the turnin of the lever V around its center p, and movingthereby through the connectinglink L and arm P the bottom I), so as toclose the vessel B again ready for the next operation.

The motion of the lever V brings the center 2 again somewhat below theline, passing through 1) and 3, after which the end of the lever Z canpass above the projection or wheel M and complete its swinging upwardmotion.

' and for the purpose substantially as described.

2. The combination of the vessel B, suspended from the beam-arms andprovided with a hinged bottom, b, the arm P, connectinglink L, lever V,provided with end projections y and M, the swinging lever Z, arm g, andthe scale-beams A, arranged to operate substantially in the manner andfor the purpose herein described.
